Gemini 3 Pro

Gemini 3 Pro is the base model of Google DeepMind’s third Gemini generation, released November 2025. It earns a page not because it is the newest model Google offers — it is not — but because every Gemini model Google shipped in 2026 descends from it, and its model card is the only document in the family that describes the architecture at all.

Its own card states that it is not itself derived from anything: “Gemini 3 Pro is not a modification or a fine-tune of a prior model.”

Gemma is Google DeepMind’s open-weight model line: the weights are published as files, and anyone can download them and run them on their own machines. It exists alongside Gemini, which is closed-weight and reachable only through Google’s interfaces. The two share research but not checkpoints — Google describes Gemma as “built from the same technology that powers our Gemini models,” not as a smaller Gemini.

The line matters for a reason that has nothing to do with capability rankings. An open-weight model can process data that must not leave a building, can be fine-tuned by a third party, cannot be withdrawn by its publisher, and can be inspected by anyone. Gemma is Google’s answer to all four, and since April 2026 its licence stops qualifying any of them.
